' The two public health interventions that have had the greatest impact on the world’s health are clean water and vaccines.'
What is immunisation?
Immunisation is a way of protecting against serious infectious diseases. Once we have been immunised, our bodies are better able to fight those diseases if we come into contact with them.
How do vaccines work?
Vaccines contain a small part of the bacterium or virus that causes a disease, or tiny amounts of the chemicals that the bacterium produces. Vaccines work by causing the body’s immune system to make antibodies (substances that fight off infection and disease). If your child comes into contact with the infection, the antibodies will recognise it and be ready to protect him or her. Because vaccines have been used so
successfully in the UK, diseases such as diphtheria have almost disappeared from this country.
There are some diseases that can kill children or cause lasting damage to their health. Immunisations are given to prepare your child’s immune system to fight off those diseases if they come into contact with them.
